Which of the following is NOT an event associated with translation termination? A stop codon enters the A site on the ribosome. A Release Factor enters the A site A terminal amino acid is added to the polypeptide to signal the end of translation. Release Factor mediates the hydrolysis of the polypeptide from the tRNA at the P site. The polypeptide and tRNA are released and the ribosomal subunits are separated.
Termination of translation occurs when: a charged tRNA gets stuck in the E site release factor enters the A site release factor enters the P site O the MRNA forms a loop structure that blocks further ribosomal function O OO 0

As you continue the translation process you will reach to the stop Codon. The stop codon brings in the release factor (a protein) that will cleave the polypeptide attached to the tRNA at the "P" site and that terminates translation: Glu Trp lle Large Ribosomal Subunit Cys His Small Ribosomal Subunit Translation of RNA into Proteins E L IRNA Ribosome Stop 5 H DAQN ALM.

Which of the following statements concerning translation is NOT correct? O b. O c. Polypeptide chain is extended from the C- terminus to the N-terminus. O d. The first codon of protein synthesis is AUG. Prokaryotic transcription and translation are coupled (i.e. they occur almost at the same time and at the same place). O e. Protein synthesis takes place in ribosome. During protein synthesis, the mRNA is read from 5' to 3' direction.

Which of the following events would NOT result in ribosomes stalling on an MRNA during translation? The MRNA in a given region is very highly folded, and the ribosome stalls because the RNA structure blocks its movement. O The correct tRNA is scarce because it is not transcribed very much in the prevailing conditions. The ribosome stalls while waiting for one of the scarce tRNAS to diffuse into the A site. O the release tactor enters the A site, decodes a stop codon and transfers an oxxYgen from water to the carboxyl group of the peptidyl-tRNA in the P site, causing stalling O Starvation for amino acids will reduce the amount of amino-acylated (charged) tRNA the ribosome will stall while waiting for a charged tRNA to enter the A site to decode the next codon

Which of the following best describes a sequence of events that happens during the elongation phase of translation?
